First, let's take a look at the macros. Each of these are listed in grams and as usual, normalized to 200 calories for easy comparison, so we're always comparing apples to apples.

| Nutrient | shrimp | eel |
| Protein | 38g | 20g |
| Carbohydrate | 2g | 0g |
| Fiber | 0g | 0g |

| Monounsat. Fat | 0g | 13g |
| Polyunsat. Fat | 1g | 1g |
| Saturated Fat | 1g | 3g |
Next, let's take a look at the Vitamin density. These values are shown in units of percent of recommended daily intake. And since we're showing 200 calories worth, this means anything above 10% is good.
| Nutrient | shrimp | eel |
| Choline | 36% | 17% |
| Vitamin A | 16% | 181% |
| Vitamin C | 5% | 3% |
| Vitamin E | 17% | 36% |

Shrimp are an excellent source of Vitamin B12. Eel are a good source of Vitamin E, Niacin. Eel are a great source of Phosphorus. Eel are an excellent source of Vitamin A, Vitamin B12.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | shrimp | eel |

| Vitamin B6 | 18% | 7% |
| Vitamin B12 | 109% | 163% |
Now, lets look at mineral density. Here we have a lot of important electrolytes and minerals. Once again, units are in percent of RDI, thus for this 200 calorie serving anything above 10% would considered high.
| Nutrient | shrimp | eel |
| Sodium | 19% | 4% |
| Potasium | 10% | 8% |
